5. A Happy Life (Dog)
Listed above most of the cast on IMDB, including several Camden family members, is the dog forever known as Happy. Happy outranks the other cast members because she made more appearances. Her story is awesome. Series creator, Brenda Hampton found Happy abandoned while on another project. She adopted the dog and came to love her so much, she wrote the little pup into the show. Happy wasn’t a Hollywood dog, requiring more training and careful treatment than normal, but people loved her. She passed in 2010 at age 15. We have to assume Happy is somewhere in the real 7th Heaven.
